GATE.

Specification of Letters Patent.

Patented Sept. 29, 1914:.

Application filed April-7, 1914. 'Serial No. 830,137.

To all whom t may concern: n

Be it known that I, ELZA R. HURsT, a citi- Zen of the United States, residing atOrient, in the county of Pickaway yand State of Ohio, have invented certain new and useful Improvements in Gates; and I dol hereby declare the following to be a full, clear, andi exact description of the invention, such asf will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw-` ings, and to the letters and figures of reference marked thereon, which form a part of this specilioation.

This invention relates to new and usefu improvements 1n automatically operated gates and especially in the provision of a tilting gate and automatic latch so arranged that, when the` gate is closed, it automatically locks and the initial raising movement of the gate preparatory to its rolling to an open position will allow the latch to be re-` leased.

My invention comprises various details of construction, combinations and arrangements of parts which will be` hereinafter fully described, shown in the accompanying drawings and then specifically definedI in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure 1 is a side elevation of the gate showing the gate closed in solid lines and open in dotted lines. Fig. 2 is a front elevation of the gate closed. Fig. 3 is an enlarged detail view of the gravity latch, Fig.

4 is an enlarged detail view showing the latch released from a catch, and Fig. 5 is a detail view showing the latch closed, the post being illustrated in section.

Reference now being had to the details of the drawings by letter, A, A designate posts which have a rod B connecting the same and upon which the upper ends of the bars B are pivoted and which latter are pivotally connected as at B2 to the angled tracks C at the longitudinal centers thereof. Levers, designated by letter D, are pivotally mounted upon the pins D carried by the bracket members E which are fastened to the post or standard and the inner end of each lever has loose pivotal connections with the curved rod F which is fastened to the upright portions of the tracks as shown. Rods F are pivotally connected to the outer ends of the levers and their lower ends pivotally connected to the angle plates I-I which i are pivoted atH to the bracket members H2, :'astened to the post. Rods I are pivotally connected oneto thel lower` end of each angle plate` and the other end to the horizontally disposed crank shaft J y having two offset' i portions .K and K over `which the wheels of a vehicle are adapted to move when traveling in one direction or the other accordingly as it may be desired to causeV the gateto be opened or closed.`

The gate, designated `by letter N, has'two end posts` O carrying bracket members O', each of which is provided with a laterally extending stub shaft Q, carrying a wheel R which is adapted `to travel upon saidtracks. A chain, designated by letter M, is fastened Vatone end to the rear .post of the gate and its other end to thetilting track and is adapted to limit the movement of the gate` in one direction to prevent the gate moving over the track when rolling yto an open position. An angled post, designated by letter T, is provided with a central slot T at its apex and the slot has a widened portion above the shoulders T2. n

' A gravity latch, designated by letter L, is pivotally mountedin a hole in the Vfront post of the gate and has its forward end L bentto form a hook and to its opposite end a weighted arm L2 is fixed, the purpose of said arm being to normally hold the hook at an inclination to the slot in said post so that," `when the gate closes, the end of the hook striking the adjacent face of the angled slotted post will cause the hook to tilt to allow the hook to pass through the slot, after which the weighted arm will return the hook to its normal position and throw the hook into a locked relation over the edge of the slot, as shown clearly in the drawings.

The operation of my invention will be readily understood and is as follows: When it is desired to open the gate, a vehicle approaching from either position and driving over one of the loops of the crank shaft may cause one or the other of the levers to be actuated to tilt the forward end of the track upward, which will cause the gate to roll by gravity to an open position. Prior to the opening of the gate, it will be necessary to release the hook from said angled post. This is accomplished during the initial operation in opening the gate, the first movement, as one or the other of the levers is tilted, causing the forward end of the gate to be raised a sufficient distance to allow the hook to pass through the widened portion ofA the slot without interference with the marginal edges of the slot. A further tilting movement of the gate will cause the latter to roll fby gravityv to an open position. When it is desired to close the gate by a vehicle passing from either direction over another loop of the crank shaft, the angled track :will be tilted back to its normal positiong and the gate will roll by gravity to its closed position and, as the hook which is normally fdisposed at anv inclination, comes in contactwith 'the inclined edge Vof the angled post, the moment-uni of the gate will cause thel lshank portion of the hook to rockto allow:

fthe hooked end to passfthrough the'slot and,

'f 'after' the hook has passed through the slot,

the weighted'arm'will return the hook to its normal position to .engage over the edge of ""Fromthe foregoing, will be noted that, by the provision of 4a gate'made in accordance with my invention, a simple andeili- Vcient `mechanism is afforded -whereby the gate is notjfonly releasediautomatically but `opened,closedand lockedby a vehicleapproaching'the gate `in either direction.`

Ixclaim to benew'is: f1; A gravity gate 'and'automatic lock comprising posts, angled tracks pivotally mountthereon, means for tiltingthetracks, a

" 'gate "having"y rollers mounted upon said Copies of this patent may be obtanedior tracks,'a vertically disposed V-shap'ed post having a slot in the ridge thereof, which slot is widened"nearitsfupper end, a latch jour-A naled in thegate'post and having oneend hooked and a counterbalance arm upon the other` end, ysaid jhook adapted,`as the gate fcloses,`to contact with the inclined face of the gate post to cause the gate to lock under the momentum of the gate closing, and a 'tracks and having loose pivotal connection with said apertures, horizontally disposed rock shafts with pivotal connections between fthe same and said levers, a gate hav- "ing' rollers at the upper ends thereof mounted un'on'said tracks, a chain fastened to one end of the gate and the other end to the track to lnnitthe movement of the gate in 'o'ne direction, a slotted V-shaped post, a

hook having a shank portion journaled in the end of the gate, vone end bent to form a hook for engage-ment with a slot in said post, and' a weighted arm upon the other end of the hook, the upper portion'of the slot be- 'ing widened to allowthe hook to withdraw when in'its normal position, said gate being adapted to be raised at its latch endso as to 'permit the latch to pass freely through said vwidened portion of the slot when the tracks are rocked'to open the gate, as set forth.

In testimony whereof I hereunto aiix my signature in the presence of two witnesses.`
